BAND-CUTTER AND FEEDER.

Specicaton of Letters Patent.

Application filed July 17,1913.

To all whom it may concern Be it known that I, OTTO FACKLAM, a subject of the Emperor of Germany, residing at Gantenbeck, near Kltz, Mecklenburg, Germany, have invented a certain Band-Outter and Feeder, of which the following is a specification.

The present invention relates to a device for opening grain sheaves and delivering them to the threshing machine, and consists in the provision of a chute over which a revolving drum is arranged, means being provided for arresting the sheaves on the chute while reciprocating cutters, connected to the drum, cut them open, the drum having a rake which, after a sheaf has'been opened, delivers the grain to the threshing machine.

1n the accompanying drawings the invention is illustrated by way of example, Figure 1 representing a side view of the machine, Fig. 2, a planvof the same, some parts being removed, Fig. 3, a sectional view of the drum, and Fig. 4, views at right angles of the link mechanism which controls the cutters. y

A machine frame 1 carries a chute 4 a small portion 5 of which is bent substantially into S-shape and formed with slots in which the free ends of arms 20, connected to a rock-shaft 21 under the chute, can be moved up and do-wn through the latter. Held in uprights on the machine frame, above the portion 5 of the chute, is a rotatable shaft 6 which is fitted at one end with a crank 22. This crank is connected by means of a rod 23 to an arm 2st which is mounted on the shaft 21 for rocking the latter. Upwardly directed tines 25 are connected to the arms 2O near the free ends so as to work in the slots in the chute when the shaft 21 is rocked.

. On the shaft 6, between the uprights, a drum 2 is mounted which is composed of two circular end walls 7 and a circumferential wall 27. A radial slot 8 in each of the walls 7 accommodates a link 9 which is pivoted at its inner end to the wall so that it can swing freely through the slot to either side of said wall. The free ends of the links are bifurcated and hold swiveled bushings 19 t) to which a rod 10 is connected so as to be held parallel with the shaft 6 while it swings with the links. A plurality of spaced cutting blades 12 is connected to the rod 10 between two pairs of tines 11. The cutters 12 and the tines 11 are held at right angles to the rod which moves these elements circularly through a longitudinal slot 28 in the wall 27 when it 1s swung on the links 9. At one end of the rod 10 a roller 17 is arranged which, in one position of the drum, engages the edge of a stationary cam 16. This cam cooperates with springs 18, acting on the links 9, for swinging the rod and operating the cutters. r

Arranged within the drum 2 so as to work behind the cutters is an eccentric shaft 13 which is rotatably held in the walls 7. One end of the shaft 13 projects through the wall 7 and is iitted with a toothed wheel 31. This wheel meshes with a wheel 30 which is equal in size to the wheel 31 and which is rigidly secured to the machine frame so as to be concentric with the shaft 6. As the drum 2 rotates, therefore, the wheel 31 and the shaft 13 will be turned about the axis of the wheel as well as about the shaft 6 at an equal ratio. The shaft 13 is fitted with tines 14 which, during one phase of the revolution, operate in the circumferential slots 29 in the wall 27 and form a kind of rake for transferring the grain to the threshing machine. The upper part of the drum 2 is covered by a concentric plate 3 or hood connected to the machine frame. A rod 15, which is arranged diametrically opposite the rod 10, connects the walls 7 for strengthening purposes.

The apparatus is mounted o-n a threshing machine, which may be of any known construction, and is driven from the latter, t-he shaft 6 being for that purpose fitted with a pulley 26.

The modas operandi is as follows The sheaves are placed on the chute A and rolled along the latter to the curved portion 5 where they are retained. As the rod 10 approaches this portion of the chute, the tines 25 are raised so as to grip the sheaf and hold it in position for being opened. Then the rod 10 is actuated by the cam 16 so as to move the cutters 12 through the slot 28 and pass them between the straws of the sheaf for cutting the band by means of which the latter is tied together. Owing to the movement of the drum 2, the cutters 12 as well as` the tines 11 at the same time tend to disperse the sheaf. As soon as the sheaf band has been cut, the tines 25 are withdrawn, and the tines 14, which have meanwhile been projected through the wall 27, rake the grain of the chute into the threshing machine. rl'his is repeated for each revolution of the drum. The length and spacing of the cutters l2, as well as the length and movement of the links 9 should be so adjusted that a cutting of the sheaf band is bound to take place even when the sheaves are irregular in size. The movement of the arms Q0 is so adjusted that the tines 25 reach the highest position only just after the cutting movement of the cutters 12 has commenced.
